n DESCRIPTION
The AIC1401 is a high efficiency, PWM step-
down, voltage-mode, switching controller. It is
suitable for IA, Notebook, LCD PC and LCD
monitor main power applications.
The built-in high voltage CMOS driver drives an
external N-channel MOSFET for replacing the
higher cost P-channel MOSFET in a standard
buck topology.
The 200KHz switching frequency allows using
smaller external components while maintaining
high conversion efficiency. The 11MHz
bandwidth and 6V/us slew rate of the error
amplifier ensures the higher converter
bandwidth and the fast transient response.
The AIC1401 also features over current
protection. It provides adjustable over current
trigger point and short-circuit protections by
sensing the output current across the on
resistance of the external N-channel MOSFET
rather then an expensive external low value
sense resistor.
